My name is Cory. Despite sharing that name with 120k other people in the U.S., occurrences of misidentification due to having the same name as somebody else are very rare and usually often resolved by merely using my last name instead.

If your apps' users report problems with identifying people, just allow users to add more specificity to their username. "People always get me confused with this other user 'chairdude', can I change my display name to 'armchairdude'?"

If thirteen 'saurik's want to have a fun time and create a confusing discussion thread together, so be it.
